Background: Nowadays, frozen-thawed embryo transfer (FET) cycles represent a high proportion of fertility treatments worldwide. Recent studies suggest differences in pregnancy outcomes depending on the FET treatment protocol used. The reason for this is still unclear, but the number of corpora lutea (CL) at conception is discussed as a possible factor. This study aims to investigate whether maternal and neonatal outcomes for pregnancies following FET lacking a CL differ from FET with one or more CL in order to explore a potential link between CL absence and adverse pregnancy outcomes.Methods: The study was designed as a retrospective, multi-center observational study with two cohorts after singleton live birth [0 CL cohort (FET in a programmed cycle, n = 114) and ≥ 1 CL cohort (FET in a natural or stimulated cycle, n = 68)]. Participants completed a questionnaire on the outcome of pregnancy and birth records were analyzed in a descriptive way. Multivariable logistic and linear regressions were performed in order to explore associations between CL absence and pregnancy outcomes. The strength of the agreement between the information in the survey and the diagnoses extracted from the files was assessed by Cohen's Kappa.Results: The risk of hypertensive disorders of pregnancy was higher after FET in the absence of a CL compared to FET with CL presence (aOR 5.56, 95% CI 1.12 – 27.72). Birthweights and birthweight percentiles were significantly higher in the 0 CL group. CL absence was a predictor of higher birthweight (adjusted coefficient B 179.74, 95% CI 13.03 – 346.44) and higher birthweight percentiles (adjusted coefficient B 10.23, 95%, 95% CI 2.28 – 18.40) particularly in female newborns of the 0 CL cohort. While the strength of the agreement between the reported information in the survey and the actual diagnoses extracted from the files was good for the majority of outcomes of interest it was fair in terms of hypertension (κ = 0.38).Conclusion: This study supports observations suggesting a potential link between a lack of CL at conception and adverse maternal and neonatal outcomes. Further investigations on causes and pathophysiological relationships are yet to be conducted.

Summary This study analyzed the effects of the day of trophectoderm (TE) biopsy and blastocyst grade on clinical and neonatal outcomes. The results showed that the implantation and live birth rates of day 5 (D5) TE biopsy were significantly higher compared with those of D6 TE biopsy. The miscarriage rate of the former was lower than that of the latter, but there was no statistically significant difference. Higher quality blastocysts can achieve better implantation and live birth rates. Among good quality blastocysts, the implantation and live birth rates of D5 and D6 TE biopsy were not significantly different. Among fair quality and poor quality blastocysts, the implantation and live birth rates of D5 TE biopsy were significantly higher compared with those of D6 TE biopsy. Neither blastocyst grade nor the day of TE biopsy significantly affected the miscarriage rate. Neonatal outcomes, including newborn sex, gestational age, preterm birth, birth weight and low birth weight in the D5 and D6 TE biopsies were not significantly different. Both blastocyst grade and the day of TE biopsy must be considered at the same time when performing preimplantation genetic testing–frozen embryo transfer.

Abstract Background: Previous studies have demonstrated that newborns from fresh embryo transfer have higher risk of small for gestation (SGA) rate than those from frozen-thawed embryo transfer (FET). It is suggested that supraphysiologic serum estradiol in controlled ovarian stimulation (COS) is one of reasons. Our study aims to investigate whether exogenous estradiol delivered regimens have an impact on live birth rate and neonatal outcomes in hormone replacement (HRT)-FET cycles. Methods: This was a retrospective study involving patients undergoing their first FET with HRT endometrium preparation followed by the transfer of two cleavage-staged embryos, comparing estradiol administered orally and vaginally (OVE group) versus estradiol administered orally (OE group) from January 2015 to December 2018 at our center. A total of 792 patients fulfilled the criteria, including 228 live birth singletons. The live birth rate was the primary outcome measure. Secondary outcome measures included clinical pregnancy rate, singleton birthweight, large for gestational age (LGA) rate, SGA rate, preterm delivery rate. Results: Patients in OVE group achieved higher serum estradiol level with more days of estradiol treatment. No difference in live birth (Adjusted OR 1.327; 95%CI 0.982, 1.794, p = 0.066) and clinical pregnancy rate (Adjusted OR 1.278; 95%CI 0.937, 1.743, p = 0.121) was found between OVE and OE groups. Estradiol route did not affect singletons birth weight (β = -30.962, SE = 68.723, p = 0.653), the odds of LGA (Adjusted OR 1.165; 95%CI 0.545, 2.490, p = 0.694), the odds of SGA (Adjusted OR 0.569; 95%CI 0.096, 3.369, p = 0.535) or the preterm delivery (Adjusted OR 0.969; 95%CI 0.292, 3.214, p = 0.959). Conclusion: Estrogen taken orally and vaginally together did not change live birth rate and singleton neonatal outcomes compared to estrogen taken orally, but was accompanied with relative higher serum E2 level and potential maternal undesirable risks.
